North Korea’s initial launch on May 31 of the new “Chollima-1” space launch vehicle (SLV), carrying the new “Malligyong-1” military reconnaissance satellite, was unsuccessful; the second stage booster apparently failed to ignite. Based on photos of the launch released in North Korean media, the first stage of the new SLV is based on the Hwasong-17 intercontinental ballistic missile (ICBM). The second and third stages appear to be optimized for space launch, with new engines and apparently differences in propellant. The cause of the failure is unknown, but South Korean authorities are working to recover the second and third stages, and perhaps even the payload, from the Yellow Sea, which would shed more light on their capabilities.
